No but guys
Everyone’s talking about the identical tie and saying it’s a hint for Mystrade (or just the bbc being short on props)
but the Mycroft we see here is in Sherlock’s mind palace
he’s wearing Lestrade’s tie because Sherlock SAW that tie at the wedding and it’s just stuck in his mind, so he subconsciously assigned it to Mycroft
it’s the same way our mind uses bits of what we see to make up dreams- we can’t ‘make up’ faces we haven’t seen before
Bottom line: Sherlock subconsciously sees a link between Lestrade and Mycroft. Sherlock totally ships them.
I’m totally okay with this.
